Noctua NF-A12x25 PWM Fan Review – ReCheck!

Output Noise

I use a Class 1 Bruel & Kjaer 2270 G4 sound analyzer equipped with a Type 4955a microphone with a dBA-weighted dynamic range of below 6 dBA and up to 110 dBA. All tests are conducted inside a hemi-anechoic chamber with a noise floor close to 6 dBA and an ambient temperature of 25–28 °C. The test subject is placed a meter from the sound analyzer.

Full & 70% Speed

Noise output is dead low.

Speed (Percentage) – Noise

I use a different setup to drive the fan for noise measurements, so there might be a difference in the readings of the Longwin machine, especially in the max fan speed reading.

  1. Hi! Thanks for such a detailed review!

    I agree, the hero of the review is far from the most productive fan in terms of noise normalization, but its quality is… a separate level

    As a person for whom complete noiselessness of assembly is a priority, I cannot accept some models following the NF-A12x25 in the list of the best, simply because, based on personal experience and numerous reviews, after a while very unusual sounds at low rpm (~800-1000 rpm) begin to emanate from them

    Therefore, in my personal top, I would give him a solid 2nd place in terms of a combination of factors
    The rest is a matter of compatibility of the Phankeks T30 with your build. 😁

    Suggestion: it would be cool to add fan testing for near-silent operation, 10 dBa, for example, there are probably a lot of silence maniacs in their builds 🙃

    Also, please test the NF-A14 (aka A15 for the NH-D15 cooler)

    Thanks!

    Happy New Year to your team! 🎄

    1. Happy New Year!

      Unfortunately, I cannot do torture testing in noise measurements, for now at least.
      This Noctua fan has sky-high quality and its bearing is among the best in today’s market, but since performance is of the highest priority, it needs improvements there.

      In the way I test, even 20 dBA is very low, since I measure the fans from 1 meter away. I also have readings for 15 dBA.
